Abstract
The utility model discloses a kind of elastic moulds for aluminium alloy reverse extrusion, including the ring that rises, pushing out ring；The ring that rises is hollow, removably the coaxial mold shaft being connected in extrusion equipment；The pushing out ring rises in ring described in being coaxially set to, and the pushing out ring is removably connected to the ring that rises.Extrusion die is set in pushing out ring, and extrusion die volume is small compared with common die, and the processing cost of mold and period are low.Extrusion die and pushing out ring clearance fit, easy for assemble or unload, extrusion die is generally applicable.The ring that rises is detachably connected with the mold shaft in extrusion equipment, the replaceable ring that rises after the ring that rises abrasion, and production cost is low；During reverse extrusion, the ring that rises expansion reduces the gap between mold and extrusion cylinder, reduces anti-aluminium when extruding, the clear aluminium time is reduced while improving product surface quality, improves production efficiency.
Description
Technical field
The utility model belongs to the manufacturing equipment field of aluminium alloy, and in particular to a kind of bullet for aluminium alloy reverse extrusion
Property mold.
Background technique
The alloy product of indirect extrusion machine production has excellent internal organizational structure and surface quality, is mainly used for giving birth to
The industry profile of high performance Aerospace Products and great surface quality is produced, there is the added value stabilized the market with superelevation, phase
For forward extrusion, product advantage is obvious.But the abrasion of extrusion cylinder, mold are controlled in the reverse extrusion of aluminium alloy
Size is less than normal, and anti-aluminium is heavier when causing to squeeze, and influences the surface quality of product, and clear aluminium then needs to consume the plenty of time, influences
The quality and production efficiency of alloy product.
Utility model content
In view of this, subtracting the purpose of this utility model is to provide a kind of elastic mould for aluminium alloy reverse extrusion
Anti- aluminium in few aluminium alloy reverse extrusion, promotes the quality and production efficiency of alloy product.
To achieve the above object, the utility model provides the following technical solutions:
A kind of elastic mould for aluminium alloy reverse extrusion, including the ring that rises, pushing out ring；The ring that rises is hollow, removably
The coaxial mold shaft being connected in extrusion equipment；The pushing out ring rises in ring described in being coaxially set to, and the pushing out ring is detachably connected
In the ring that rises.
Optionally, extrusion die, the extrusion die and the pushing out ring clearance fit are coaxially provided in the pushing out ring.
Optionally, the outside of the pushing out ring is the round-like structure that can make the ring extension of rising.
Optionally, the ring that rises is connect by bolt with the mold shaft.
Optionally, the bolt is positioning bolt.
Optionally, the pushing out ring is connect by positioning jackscrew with the ring that rises.
Optionally, the pushing out ring and the interannular that rises are additionally provided with locking jackscrew.
The utility model has the beneficial effects that: extrusion die is set in pushing out ring in the utility model, extrusion die is specific
Product is small compared with common die, reduces processing cost and the period of mold.Extrusion die and pushing out ring clearance fit, installing and dismounting side
Just, the replacement efficiency of mold is improved, while can realize that the extrusion die of different tonnage indirect extrusion machines is general, improves production
Efficiency.The ring that rises is detachably connected with the mold shaft in extrusion equipment, and the replaceable ring that rises after the ring that rises abrasion is significantly reduced and is produced into
This.During reverse extrusion, the ring that rises expansion reduces the gap between mold and extrusion cylinder, reduces anti-aluminium when extruding, promoted
Reduce the clear aluminium time while surface quality of product, improves production efficiency.
Detailed description of the invention
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows
Attached drawing:
Fig. 1 is the elastic mould structural schematic diagram for aluminium alloy reverse extrusion
Specific embodiment
The preferred embodiment of the utility model will be described in detail below.Actual conditions are not specified in embodiment
Experimental method, usually according to conventional conditions or according to the manufacturer's recommendations.
Referring to Fig. 1, the utility model is a kind of elastic mould for aluminium alloy reverse extrusion, including rise ring 1, pushing out ring
2, the ring 1 that rises is hollow, removably the coaxial mold shaft 6 being connected in extrusion equipment；In the present embodiment, it is fixed that the ring 1 that rises passes through with mold shaft 6
Position bolt 7 connects；Pushing out ring 2 is coaxially set to described rise in ring 1.In the present embodiment, pushing out ring 2 positions jackscrew 4 by jackscrew and connects
It is connected to the ring 1 that rises, locking jackscrew 5 is additionally provided between pushing out ring 2 and the ring 1 that rises, is coaxially provided with extrusion die 3 in pushing out ring 2.The present embodiment
In, extrusion die 3 and 1 clearance fit of pushing out ring.
In actual use, elastic mould squeezes aluminium alloy bar, and extrusion die 3 and pushing out ring 2 act on aluminium alloy
Bar, extrusion die 3 and pushing out ring 2 are acted on and are risen by the axial deformation after axial reaction force, 2 stress of pushing out ring of aluminium alloy bar
Ring 1, radial dilatation after 1 stress of ring that makes to rise, diameter becomes larger, reduces with extrusion cylinder gap, thus anti-aluminium when reducing reverse extrusion,
The product surface quality of extrusion is improved, reduces the activity duration of clear aluminium, improves production efficiency.
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
